  1. 16. No time to waste : Pre-hospital actions and time delays in patients with ST elevation myocardial infarction – temporal trends and prognostic impact on short- and long-term survival

    Författare :Maria Ericsson; Ingela Thylén; Anna Strömberg; Sofia Sederholm Lawesson; Emil Hagström; Linköpings universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

    Sammanfattning : Background: In ST-elevation myocardial infarction (STEMI) patients, a rapid diagnosis is imperative to reduce total ischaemic time minimizing risk for heart failure, serious arrhythmias, or death. Prehospital context is complex, and the patient delay constitute major part of the pre-hospital phase. LÄS MER

  3. 17. Performance Analysis of Positive Systems and Optimization Algorithms with Time-delays

    Författare :Hamid Reza Feyzmahdavian; Mikael Johansson; Peter Richtarik; KTH; []
    Nyckelord :Optimization; Delay; Positive system; Asynchronous; Electrical Engineering; Elektro- och systemteknik;

    Sammanfattning : Time-delay dynamical systems are used to model many real-world engineering systems, where the future evolution of a system depends not only on current states but also on the history of states. For this reason, the study of stability and control of time-delay systems is of theoretical and practical importance. LÄS MER

  4. 18. Symptoms, prehospital delay and long-term survival in men vs. women with myocardial infarction : a combined register and qualitative study

    Författare :Rose-Marie Isaksson; Mats Eliasson; Christine Brulin; Karin Zingmark; Bengt Fridlund; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; myocardial infarction; symptoms; prehospital delay; men and women; long-term survival; time trend; experiences; Nursing; Omvårdnad; omvårdnadsforskning med medicinsk inriktning; Caring Sciences;

    Sammanfattning : The general aim of this thesis was to study symptoms, prehospital delay and time trends in long-term survival in men and women with myocardial infarction (MI). The study was based on quantitative and qualitative data collections. LÄS MER

  5. 19. Probabilistic time estimation in tunnel projects

    Författare :Mohammad Mohammadi; Johan Spross; Fredrik Johansson; Larsson Stefan; Anna Kadefors; Lars-Olof Dahlström; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Cost overrun; Tunneling projects; Probabilistic approaches; time estimation; Kostnadsöverskridande; tunnelprojekt; sannolikhetsmetoder; tidsuppskattning; Soil and Rock Mechanics; Jord- och bergmekanik;

    Sammanfattning : Transport infrastructure projects, including tunneling, suffer from timedelays and cost overrun. A literature review shows that the effect ofuncertainty has been neglected in explaining time and cost overrunmeaning that technical explanations matter. LÄS MER

  7. 20. Flexible Scheduling Methods and Tools for Real-Time Control Systems

    Författare :Dan Henriksson; Institutionen för reglerteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Model Predictive Control; Simulation Tools; Delay Compensation; Feedback Scheduling; Real-Time Control;

    Sammanfattning : This thesis deals with flexibility in the design of real-time control systems. By dynamic resource scheduling it is possible to achieve on-line adaptability and increased control performance under resource constraints. The approach requires simulation tools for control and real-time systems co-design. LÄS MER
